COMPLETE STUDY GUIDE
●● Recommended guidelines state that HSV can be considered when....
Answer: Cheyne Stokes and central Apneas have not been eliminated.
●● What is aerophagia?
Answer: The swallowing of air
●● What is maxillomandibular advancement?
Answer: Treatment that involves cutting and advancing the upper and
lower jaw bones; enlarging and stabilizing the posterior airway.
●● What is the PRIMARY function of the EPAP setting?
Answer: To eliminate desaturations and arousals.
●● According to guidelines, how many Hypopneas need to occur in peds
pts prior to increasing pressure?
Answer: 1
,●● What are the AASM guidelines for supplemental O2 during PAP
studies?
Answer: 1lmp during PAP titration when SPO2 is less than or equal to
88% for 5 or more minutes and in the absence of obstructive events.
●● If a pts Apneas are fixed at 10cm, but Hypopneas and snoring still
occur at 16cm, what levels of BiLevel should be used?
Answer: IPAP: 14
EPAP: 10
●● Which of the following can reduce the effectiveness of CPAP and
why: Nasal spray, Alcohol, Anti depressants.
Answer: Alcohol: impairs arousal response which can lead to longer
than normal events and severe desats. Inhibits upper airway activity
●● What syndrome would a pt with COPD and OSA have?
Answer: Overlap syndrome
●● What are hypoxemia and hypercapnia?
Answer: Hypoxemia: very low 02 in the blood
Hypercapnia: very high CO2 in the blood.
●● What would a patient with both hypoxemia and hypercapnia most
likely be diagnosed with?
,Answer: Hypoventilation
●● What is an MWT's MOST important use?
Answer: Measure patients ability to resist the urge to fall asleep
●● Tricyclic antidepressants, large amounts of caffeine and large
amounts of chocolate have been known to trigger what?
Answer: REM sleep behavior disorder
●● Recommended impedance for eeg and eog
Answer: 5k ohms
●● The amount of space needed to archive digitized data is MOST
impacted by?
Answer: Sampling rate
●● Cortical activity is best described as
Answer: Spontaneous arousal
●● Calculate the AHI based on the following data
25 obstructive apneas
5 central apneas
23 mixed apneas
, 15 hypopneas
48 RERAS
65 arousals
360 min of sleep
Answer: 11
●● According to RECOMMENDED guidelines, the minimum duration
of a significant leg movement is
Answer: .5
●● According to RECOMMENDED guidelines, an optional parameter
to include in the report for an adult polysomnogram is
Answer: Occurrence of hypoventilation during the diagnostic study in
adult
●● The respiratory event that requires oxygen desaturation and/ or an
arousal as part of the scoring criteria is
Answer: Obstructive hypopnea
●● An ECG arrhythmia commonly seen when recording PSG's,
particularly in patients that have obstructive sleep apnea and cardiac
disease. It can be identified by the morphology of an irregularly irregular
ventricular rhythm associated with replacement of consistent P waves by
rapid oscillations that vary in size, shape, and timing
